Features:
1. This module can convert 0- PWM digital signal into analog signal.
2. The input digital signal can be a 0- PWM signal of 3.3V level.
3. The output analog signal can be 0-10V voltage.
4. Widely used in signal interface switching of PLC, single chip or other industrial control board.
5. The power supply has reverse polarity protection function.
Specification:
1. Model: 3.3P-5V
Function: Input 0- PWM signal of 3.3V level, output 0-10V voltage
2. PWM Signal Receive Frequency Range: 100HZ-3KHZ (1-3KHZ is recommended)
3. Insert the jump pin at 5V
4. Analog Voltage Output: The following is the output voltage of 0-10V to illustrate
After power-on, when there is no input signal, the output is 0V
For the first power-up, a calibration can be done: Input a signal with 50% duty cycle and 3.3V amplitude to DIN- and DIN+. The frequency is 1-3KHZ. Use a multimeter to measure two ports of AO and GND. Adjust the potentiometer on the board to make the multimeter display 5.40V. This calibrate the corresponding relation between pulse signal and this module. The resolution of this module is 0.1V. The output current capability is 10MA. If the percentage of the duty cycle is inversely related to the voltage, you can chefor CK the chefor CK box of STEP LOW, ACTIVE to set the pins of PWM output in the MACH3 software.
5. Supply Voltage: 15-30VDC (power requirement of power supply: >100MA), 12V customizable
6. Output Power: About 10MA
7. Mounting Method: 4 * M3 screw hole
Port:
1. DIN+: Positive of PWM signal (For common cathode, connect it to PWM signal; For common anode, connect it to 3.3V of signal terminal)
2. DIN-: Negative of PWM signal (For common cathode, connect it to GND; For common anode, connect it to PWM signal)
3. 12-30V: Positive of power supply
4. GND: Ground of power supply
5. GND: Ground of power supply. It is connected to ground of power supply
6. AO: Output port of analog voltage (0-10V)
